MAME 0.219

MAME 0.219 arrives today, just in time for the end of February! This month we’ve got another piece of Nintendo Game & Watch history – Pinball – as well as a quite a few TV games, including Dream Life Superstar, Designer’s World, Jenna Jameson’s Strip Poker, and Champiyon Pinball. The previously-added Care Bears and Piglet’s Special Day TV games are now working, as well as the big-endian version of the MIPS Magnum R4000. As always, the TV games vary enormously in quality, from enjoyable titles, to low-effort games based on licensed intellectual properties, to horrible bootlegs using blatantly copied assets. If music/rhythm misery is your thing, there’s even a particularly bad dance mat game in there.
On the arcade side, there are fixes for a minor but long-standing graphical issue in Capcom’s genre-defining 1942, and also a fairly significant graphical regression in Seibu Kaihatsu’s Raiden Fighters. Speaking of Seibu Kaihatsu, our very own Angelo Salese significantly improved the experience in Good E-Jan, and speaking of graphics fixes, cam900 fixed some corner cases in Data East’s innovative, but little-known, shoot-’em-up Boogie Wings. Software list additions include the Commodore 64 INPUT 64 collection (courtesy of FakeShemp) and the Spanish ZX Spectrum Load’N’Run collection (added by ICEknight). New preliminary CPU cores and disassemblers include IBM ROMP, the NEC 78K family, Samsung KS0164 and SSD Corp’s Xavix 2.
As always, you can get the source and 64-bit Windows binary packages from the download page.

Boolean data type

From Wikipedia, the free encyclopedia Jump to navigation Jump to search
In computer science, the Boolean data type is a data type that has one of two possible values (usually denoted true and false) which is intended to represent the two truth values of logic and Boolean algebra. It is named after George Boole, who first defined an algebraic system of logic in the mid 19th century. The Boolean data type is primarily associated with conditional) statements, which allow different actions by changing control flow depending on whether a programmer-specified Boolean condition evaluates to true or false. It is a special case of a more general logical data type (see probabilistic logic)—logic doesn't always need to be Boolean.

Contents


Generalities

In programming languages with a built-in Boolean data type, such as Pascal) and Java), the comparison operators such as > and ≠ are usually defined to return a Boolean value. Conditional and iterative commands may be defined to test Boolean-valued expressions.
Languages with no explicit Boolean data type, like C90 and Lisp), may still represent truth values by some other data type. Common Lisp uses an empty list for false, and any other value for true. The C programming language uses an integer) type, where relational expressions like i > j and logical expressions connected by && and || are defined to have value 1 if true and 0 if false, whereas the test parts of if , while , for , etc., treat any non-zero value as true.[1][2] Indeed, a Boolean variable may be regarded (and implemented) as a numerical variable with one binary digit (bit), which can store only two values. The implementation of Booleans in computers are most likely represented as a full word), rather than a bit; this is usually due to the ways computers transfer blocks of information.
Most programming languages, even those with no explicit Boolean type, have support for Boolean algebraic operations such as conjunction (AND , & , * ), disjunction (OR , | , + ), equivalence (EQV , = , == ), exclusive or/non-equivalence (XOR , NEQV , ^ , != ), and negation (NOT , ~ , ! ).
In some languages, like Ruby), Smalltalk, and Alice) the true and false values belong to separate classes), i.e., True and False , respectively, so there is no one Boolean type.
In SQL, which uses a three-valued logic for explicit comparisons because of its special treatment of Nulls), the Boolean data type (introduced in SQL:1999) is also defined to include more than two truth values, so that SQL Booleans can store all logical values resulting from the evaluation of predicates in SQL. A column of Boolean type can also be restricted to just TRUE and FALSE though.

ALGOL and the built-in boolean type

One of the earliest programming languages to provide an explicit boolean data type is ALGOL 60 (1960) with values true and false and logical operators denoted by symbols ' ∧ {\displaystyle \wedge } 📷' (and), ' ∨ {\displaystyle \vee } 📷' (or), ' ⊃ {\displaystyle \supset } 📷' (implies), ' ≡ {\displaystyle \equiv } 📷' (equivalence), and ' ¬ {\displaystyle \neg } 📷' (not). Due to input device and character set limits on many computers of the time, however, most compilers used alternative representations for many of the operators, such as AND or 'AND' .
This approach with boolean as a built-in (either primitive or otherwise predefined) data type was adopted by many later programming languages, such as Simula 67 (1967), ALGOL 68 (1970),[3] Pascal) (1970), Ada) (1980), Java) (1995), and C#) (2000), among others.

Fortran

The first version of FORTRAN (1957) and its successor FORTRAN II (1958) have no logical values or operations; even the conditional IF statement takes an arithmetic expression and branches to one of three locations according to its sign; see arithmetic IF. FORTRAN IV (1962), however, follows the ALGOL 60 example by providing a Boolean data type (LOGICAL ), truth literals (.TRUE. and .FALSE. ), Boolean-valued numeric comparison operators (.EQ. , .GT. , etc.), and logical operators (.NOT. , .AND. , .OR. ). In FORMAT statements, a specific format descriptor ('L ') is provided for the parsing or formatting of logical values.[4]

Lisp and Scheme

The language Lisp) (1958) never had a built-in Boolean data type. Instead, conditional constructs like cond assume that the logical value false is represented by the empty list () , which is defined to be the same as the special atom nil or NIL ; whereas any other s-expression is interpreted as true. For convenience, most modern dialects of Lisp predefine the atom t to have value t , so that t can be used as a mnemonic notation for true.
This approach (any value can be used as a Boolean value) was retained in most Lisp dialects (Common Lisp, Scheme), Emacs Lisp), and similar models were adopted by many scripting languages, even ones having a distinct Boolean type or Boolean values; although which values are interpreted as false and which are true vary from language to language. In Scheme, for example, the false value is an atom distinct from the empty list, so the latter is interpreted as true.

Pascal, Ada, and Haskell

The language Pascal) (1970) introduced the concept of programmer-defined enumerated types. A built-in Boolean data type was then provided as a predefined enumerated type with values FALSE and TRUE . By definition, all comparisons, logical operations, and conditional statements applied to and/or yielded Boolean values. Otherwise, the Boolean type had all the facilities which were available for enumerated types in general, such as ordering and use as indices. In contrast, converting between Boolean s and integers (or any other types) still required explicit tests or function calls, as in ALGOL 60. This approach (Boolean is an enumerated type) was adopted by most later languages which had enumerated types, such as Modula, Ada), and Haskell).

C, C++, Objective-C, AWK

Initial implementations of the language C) (1972) provided no Boolean type, and to this day Boolean values are commonly represented by integers (int s) in C programs. The comparison operators (> , == , etc.) are defined to return a signed integer (int ) result, either 0 (for false) or 1 (for true). Logical operators (&& , || , ! , etc.) and condition-testing statements (if , while ) assume that zero is false and all other values are true.
After enumerated types (enum s) were added to the American National Standards Institute version of C, ANSI C (1989), many C programmers got used to defining their own Boolean types as such, for readability reasons. However, enumerated types are equivalent to integers according to the language standards; so the effective identity between Booleans and integers is still valid for C programs.
Standard C) (since C99) provides a boolean type, called _Bool . By including the header stdbool.h , one can use the more intuitive name bool and the constants true and false . The language guarantees that any two true values will compare equal (which was impossible to achieve before the introduction of the type). Boolean values still behave as integers, can be stored in integer variables, and used anywhere integers would be valid, including in indexing, arithmetic, parsing, and formatting. This approach (Boolean values are just integers) has been retained in all later versions of C. Note, that this does not mean that any integer value can be stored in a boolean variable.
C++ has a separate Boolean data type bool , but with automatic conversions from scalar and pointer values that are very similar to those of C. This approach was adopted also by many later languages, especially by some scripting languages such as AWK.
Objective-C also has a separate Boolean data type BOOL , with possible values being YES or NO , equivalents of true and false respectively.[5] Also, in Objective-C compilers that support C99, C's _Bool type can be used, since Objective-C is a superset of C.

Perl and Lua

Perl has no boolean data type. Instead, any value can behave as boolean in boolean context (condition of if or while statement, argument of && or || , etc.). The number 0 , the strings "0" and "" , the empty list () , and the special value undef evaluate to false.[6] All else evaluates to true.
Lua) has a boolean data type, but non-boolean values can also behave as booleans. The non-value nil evaluates to false, whereas every other data type always evaluates to true, regardless of value.

Tcl

Tcl has no separate Boolean type. Like in C, the integers 0 (false) and 1 (true - in fact any nonzero integer) are used.[7]
Examples of coding:
set v 1 if { $v } { puts "V is 1 or true" }
The above will show "V is 1 or true" since the expression evaluates to '1'
set v "" if { $v } ....
The above will render an error as variable 'v' cannot be evaluated as '0' or '1'

Python, Ruby, and JavaScript

Python), from version 2.3 forward, has a bool type which is a subclass) of int , the standard integer type.[8] It has two possible values: True and False , which are special versions of 1 and 0 respectively and behave as such in arithmetic contexts. Also, a numeric value of zero (integer or fractional), the null value (None ), the empty string), and empty containers (i.e. lists), sets), etc.) are considered Boolean false; all other values are considered Boolean true by default.[9] Classes can define how their instances are treated in a Boolean context through the special method __nonzero__ (Python 2) or __bool__ (Python 3). For containers, __len__ (the special method for determining the length of containers) is used if the explicit Boolean conversion method is not defined.
In Ruby), in contrast, only nil (Ruby's null value) and a special false object are false, all else (including the integer 0 and empty arrays) is true.
In JavaScript, the empty string ("" ), null , undefined , NaN , +0, −0 and false [10] are sometimes called falsy (of which the complement) is truthy) to distinguish between strictly type-checked and coerced Booleans.[11] As opposed to Python, empty containers (arrays , Maps, Sets) are considered truthy. Languages such as PHP also use this approach.

Next Generation Shell

Next Generation Shell, has Bool type. It has two possible values: true and false . Bool is not interchangeable with Int and have to be converted explicitly if needed. When a Boolean value of an expression is needed (for example in if statement), Bool method is called. Bool method for built-in types is defined such that it returns false for a numeric value of zero, the null value, the empty string), empty containers (i.e. lists), sets), etc.), external processes that exited with non-zero exit code; for other values Bool returns true. Types for which Bool method is defined can be used in Boolean context. When evaluating an expression in Boolean context, If no appropriate Bool method is defined, an exception is thrown.

SQL

Main article: Null (SQL) § Comparisons with NULL and the three-valued logic (3VL)#Comparisonswith_NULL_and_the_three-valued_logic(3VL))
Booleans appear in SQL when a condition is needed, such as WHERE clause, in form of predicate which is produced by using operators such as comparison operators, IN operator, IS (NOT) NULL etc. However, apart from TRUE and FALSE, these operators can also yield a third state, called UNKNOWN, when comparison with NULL is made.
The treatment of boolean values differs between SQL systems.
For example, in Microsoft SQL Server, boolean value is not supported at all, neither as a standalone data type nor representable as an integer. It shows an error message "An expression of non-boolean type specified in a context where a condition is expected" if a column is directly used in the WHERE clause, e.g. SELECT a FROM t WHERE a , while statement such as SELECT column IS NOT NULL FROM t yields a syntax error. The BIT data type, which can only store integers 0 and 1 apart from NULL, is commonly used as a workaround to store Boolean values, but workarounds need to be used such as UPDATE t SET flag = IIF(col IS NOT NULL, 1, 0) WHERE flag = 0 to convert between the integer and boolean expression.
In PostgreSQL, there is a distinct BOOLEAN type as in the standard[12] which allows predicates to be stored directly into a BOOLEAN column, and allows using a BOOLEAN column directly as a predicate in WHERE clause.
In MySQL, BOOLEAN is treated as an alias as TINYINT(1)[13], TRUE is the same as integer 1 and FALSE is the same is integer 0.[14], and treats any non-zero integer as true when evaluating conditions.
The SQL92 standard introduced IS (NOT) TRUE, IS (NOT) FALSE, IS (NOT) UNKNOWN operators which evaluate a predicate, which predated the introduction of boolean type in SQL:1999
The SQL:1999 standard introduced a BOOLEAN data type as an optional feature (T031). When restricted by a NOT NULL constraint, a SQL BOOLEAN behaves like Booleans in other languages, which can store only TRUE and FALSE values. However, if it is nullable, which is the default like all other SQL data types, it can have the special null) value also. Although the SQL standard defines three literals) for the BOOLEAN type – TRUE, FALSE, and UNKNOWN – it also says that the NULL BOOLEAN and UNKNOWN "may be used interchangeably to mean exactly the same thing".[15][16] This has caused some controversy because the identification subjects UNKNOWN to the equality comparison rules for NULL. More precisely UNKNOWN = UNKNOWN is not TRUE but UNKNOWN/NULL.[17] As of 2012 few major SQL systems implement the T031 feature.[18] Firebird and PostgreSQL are notable exceptions, although PostgreSQL implements no UNKNOWN literal; NULL can be used instead.[19]

Problem running php on nginx ubuntu (files get downloaded)

Hi everyone,
I'm very new to php and ran into some issue that I have been trying to fix for a couple of hours.
I have setup Nginx on ubuntu 19.10, and installed php7.4-fpm. But whenever I try to open a file like index.php, located in my root folder /vawww/html (so localhost/index.php) it will download the file instead of running it.
Nginx is not communicating with php7.4-fpm, is my guess, but I can not find the mistake in my configuration files..

Could anyone take a look and spot what would be wrong.
Below I've put the files, in order
  1. /etc/nginx/fastcgi.conf:
  2. /etc/nginx/fastcgi_params:
  3. /etc/nginx/sites-enabled/server.conf
  4. /etc/nginx/mime.types
  5. /etc/php/7.4/fpm/php-fpm.conf
  6. /etc/php/7.4/fpm/pool.d/www.conf
  7. selection of /etc/php/7.4/fpm/php.ini since posting it all is too long
  8. output service nginx status & service php7.4-fpm status

If I'm looking at the wrong files or something and the error could be located elsewhere please guide me in the right direction.
And if you already read this far, I would like to thank you for your time!

MAME 0.219

MAME 0.219

MAME 0.219 arrives today, just in time for the end of February! This month we’ve got another piece of Nintendo Game & Watch history – Pinball – as well as a quite a few TV games, including Dream Life Superstar, Designer’s World, Jenna Jameson’s Strip Poker, and Champiyon Pinball. The previously-added Care Bears and Piglet’s Special Day TV games are now working, as well as the big-endian version of the MIPS Magnum R4000. As always, the TV games vary enormously in quality, from enjoyable titles, to low-effort games based on licensed intellectual properties, to horrible bootlegs using blatantly copied assets. If music/rhythm misery is your thing, there’s even a particularly bad dance mat game in there.
On the arcade side, there are fixes for a minor but long-standing graphical issue in Capcom’s genre-defining 1942, and also a fairly significant graphical regression in Seibu Kaihatsu’s Raiden Fighters. Speaking of Seibu Kaihatsu, our very own Angelo Salese significantly improved the experience in Good E-Jan, and speaking of graphics fixes, cam900 fixed some corner cases in Data East’s innovative, but little-known, shoot-’em-up Boogie Wings. Software list additions include the Commodore 64 INPUT 64 collection (courtesy of FakeShemp) and the Spanish ZX Spectrum Load’N’Run collection (added by ICEknight). New preliminary CPU cores and disassemblers include IBM ROMP, the NEC 78K family, Samsung KS0164 and SSD Corp’s Xavix 2.
As always, you can get the source and 64-bit Windows binary packages from the download page.

When dealing with binary data in PHP there are 2 main functions that you cannot live without. The pack() and unpack() functions take a (binary) string and convert them into an array. Both work more or less the same way. pack() will store an array back into a binary structure, while unpack() will do the opposite. Today’s practice algorithm question is to generate all binary code string with K. Let’s begin! Problem. Given an integer K, return a list of all possible binary code string with length K. Binary code string is a string containing only "0" and "1". The order of the return list does not matter. For example: In PHP, a null byte in a string does NOT count as the end of the string, and any null bytes are included in the length of the string. For example, in PHP: strlen( "te\0st" ) = 5 In C, the same call would return 2. Thus, PHP's strlen function can be used to find the number of bytes in a binary string (for example, binary data returned by base64 ... I've performed a simple speed test. sprintf against PHP string concatenation operator. Test was performed on PHP 7.3 for 1 million interations. I run this several times and what I've noted that string concatenation took about 2.9 seconds, sprintf took 4.3 seconds. If string length is greater than or equal to the padding length, the whole string is returned — i.e. no characters are chopped off. Please bear in mind that padding is only added when the length of the input string is smaller than the specified padding length. Refer to the sprintf() function's documentation for all the formatting options. Wednesday, 23 August 2017. Php String Length Binary Options In PHP all strings are binary (as of current PHP 5.3), so there is no way to differ. So you can not differentiate if the argument is binary data or a filename technically (a string or a string). You can however create a second function that deals with files which is re-using the function that deals with the image data. So the name of the ...
